From 3fcc3af4d270dac159fc0c8b2a28ae4f9198befe Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 1 Oct 2014 19:57:20 -0600 Subject: [PATCH] dm: linker_lists: Add a way to declare multiple objects The existing ll_entry_declare() permits a single element of the list to be added to a linker list. Sometimes we want to add several objects at once. To avoid lots of messy declarations, add a macro to support this.
